Several Warning lights coming on

when i started the truck the other morning all sorts of warning lights came on. Park brake malfunction, service electronic limited slip, check 4x4, memory recall not permitted while driving, service advance trac. I restarted the truck twice and it has since gone away and not come back. Has anyone else experienced this. Im gonna bring it to the dealer after the holidays but have a feeling they are gonna say that there is nothing wrong with it at this moment.

What is mileage? I think this came up a while back where it seemed to happen at about 12,000 miles.

Sounds like a low battery. These vehicles are sensitive to low battery voltage.

16k

It sounds like a battery issue to me too.

Yup. Low battery. Typical in all modern vehicles with a high draw like these. Put it on a charger if you have one. 99% chance the issues will go away and will stay away until the battery drops again. If you're doing a lot of short trips and the cold weather has set in, that's the tell tale.

Did the door proximity sensors stop working, too?

Same thing happened to me 7-8 months ago. Probably a coincidence, but the next day the cam phaser rattle started. I had the cam phaser repair/replacement done shortly thereafter, at about 14,000 miles.
BTW, there was an error code recorded on my FordPass app - Powertrain Malfunction / Reduced Power

Hopefully it is just a battery which is frustrating because the truck is less than 3 years old but i guess that is better than electrical gremlins.

These batteries are "designed" to las the length of the 3/36K warranty. My guess is you have had your first few days that it got cold at night. That is when a weak battery will go south. Also, PLEASE do not go out and get the cheapest battery out there. Get an AGM(Platinum) or "Gold" battery. Not only is the warranty going to be longer, the voltage is more consistent, especially on the AGM. Like was mentioned above, LOTS of electronics, consistent power is important.

PS - By any chance was your Auto Start/Stop disabled with FORSCAN?

I've had that happen to me under 5k. It was a a few months old at that point so everything was practically brand new. Never set any codes and everything checked out fine. I restarted twice and then eventually just ignored it and drove it. Has yet to ever happen again and I'm sitting at 30k. Recently I've had the auto start/stop no longer kicking in, so my guess is the battery is on it's way out. I load tested and it still showed to be good, but hopefully dealer will warranty it since the auto start/stop isn't working and the system not being charged (Fully) is usually the reason it won't kick in. Could be an alternator, but unlikely...at the dealer now so we'll see.
